Why convert AVIF to WebP?
Some CMS platforms, image tools and older Safari versions handle WebP but not AVIF. Converting gives you a widely supported modern format while keeping files far smaller than JPG or PNG.
Does converting AVIF to WebP affect quality or size?
Expect the WebP to be somewhat larger than the AVIF — typically 20–40% — at similar visual quality. Transparency carries over. Both formats are lossy, so keep quality at 80 or above to avoid compounding artefacts.
What's the difference between AVIF and WebP?
AVIF is a modern format based on the AV1 video codec. It often produces files about half the size of JPG with fewer artefacts, and supports transparency and HDR.
WebP is Google's web image format. It supports lossy and lossless compression, transparency and animation, and is typically 25–35% smaller than JPG at similar quality.
